Infections related to modern surgical procedures present a difficult problem for contemporary medicine. Infections acquired during surgery represent a risk factor related to therapeutical interventions. Eradication of microorganisms from hospital operating theatre environment may contribute to reduction of infections as the laminar flow air-conditioning considerably reduces the number of microorganisms in the hospital environment. The objective of the study was to evaluate the occurrence of fungi in air-conditioned operating theatre rooms. The study was carried out in one of the hospitals in Kraków during December 2009. Indoor air samples and imprints from the walls were collected from five operating theatre rooms. A total of fifty indoor air samples were collected with a MAS-100 device, and twenty five imprints from the walls were collected using a Count Tact method. Fungal growth was observed in 48 air samples; the average numbers of fungi were within the range of 5–100 c.f.u. in one cubic metre of the air. Fungi were detected only in four samples of the wall imprints; the number of fungi was 0.01 c.f.u. per one square centimetre of the surface. The mould genus Aspergillus was most frequently isolated, and the species A. fumigatus and A. versicolor were the dominating ones. To ensure microbiological cleanness of hospital operating theatre, the air-conditioning system should be properly maintained. Domination of the Aspergillus fungi in indoor air as well as increase in the number of moulds in the samples taken in evenings (p<0.05) may suggest that the room decontamination procedures were neglected.

The majority of mycotoxins produced by Aspergillus fungi are immunosuppressive agents, and their cytotoxicity may impair defense mechanisms in humans. The objective of the study was evaluation of the cytotoxicity of fungi isolated from an environment where inpatients with impaired immunity were present. The materials comprised 57 fungal strains: Aspergillus fumigatus, Aspergillus niger. Aspergillus ochraceus, Aspergillus flavus, Aspergillus versicolor and Aspergillus ustus isolated from hospital rooms in Cracow. The cytotoxicity of all the strains was evaluated using the MTT test (3-(4,5-dimethylthiazol-2-yl) 2,5 diphenyltetrazolium bromide). To emphasize the differences in cytotoxicity among the particular strains, variance analysis (ANOVA) and Tukey's difference test were used. Out of 57 Aspergillus strains tested, 48 (84%) turned out to be cytotoxic. The cytyotoxicity was high (+++) in 21 strains, mainly in A. fumigatus. The least cytotoxic were A. niger fungi, this being statistically significant (p<0,05). To protect a patient from the adverse effects of mycotoxins, not only his or her immunity status should be evaluated but also the presence of fungi in hospital environment and their cytotoxicity should be monitored (possible exposure).

Despite a significant civilization advancement, parasitic diseases still pose a serious diagnostic and therapeutic problem. Children’s susceptibility to these infections stems from their immature immune system and lack of basic hygiene routines. The objective of the study was to evaluate the level of knowledge which parents of preschool children’s possess about parasitic diseases in their children’s environment. The study was carried out in the group of 151 parents of preschool children living both in the city and in the country. The survey was carried out by means of a diagnostic poll with the application of a self-designed research questionnaire. To make the evaluation even more objective, a special scale was created in which parents could score points for their answers (0 – wrong answer, 1 – correct answer). The total number of points ranging from 0 to 9 indicated an unsatisfactory level of knowledge, from 10 to 13 – satisfactory level, from 14 to 16 – good level and from 17 to 20 – very good level of parents’ awareness. The results of the study reveal that the level of parents’ knowledge about parasitic diseases is only satisfactory. A statistically significant relationship was observed between the variables such as education and sex. The higher education, the higher level of knowledge. Moreover, women were more knowledgeable in the field of parasitic diseases than men were. Financial status of the family did not influence the level of parents’ awareness. Well-planned educational programmes might have a positive influence on developing proper hygiene routines in families, which, in turn, will limit the risk of spreading parasitoses in the population of children.

A tracheotomy tube, as well as the stoma through which it is inserted into the patient’s throat, may represent a potential risk of fungal infections for patients suffering from larynx cancer. The study was aimed at evaluating the influence of the hospital room environment on the fungal colonisation of tracheotomy tubes in the case of patients diagnosed with larynx cancer and operated on in the Laryngology ward. The mycological research was carried out in the rooms of the Laryngology ward, from which 105 air samples were collected. Twenty-two Portex and metal tracheostomy tubes collected from 13 patients diagnosed with larynx cancer. Fungi were cultured on 15 tracheostomy tubes: moulds were isolated from 3 of these tubes, and fungi belonging to the genus Candida from the remaining 12. The simultaneous occurrence of the same moulds in the air and on the tracheotomy tubes was observed only in one case (Aspergillus flavus). In conclusion, the same moulds observed in the air can sometimes also be found on the tracheotomy tubes used by patients diagnosed with larynx cancer. Yeast-like fungi are isolated from tracheotomy tubes much more frequently than moulds, and this requires further mycological research.
